Latch Circuit Control to Block High-Level Set/Reset Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Latch circuits experience current leakage and increased power consumption when set or reset signals are at a high level, leading to potential functional failures.
Innovation Solution
A latch circuit comprising a transmission module, a latch module, and a control module, where the control module prevents current leakage by managing the input signal or clock signals when the set or reset signal is high, either by turning off the transmission module or controlling the signal levels to avoid leakage paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the latch circuit operates with set or reset signals at high level, then the latch function can be performed, but current leakage path is generated leading to increased power consumption
Solution Approach 1:
A control module is introduced as an intermediary between the transmission module and latch module. This control module receives the set signal and reset signal, and based on their logic levels, controls the transmission module to prevent current leakage while ensuring the latch function operates correctly. The control module mediates between the conflicting requirements of maintaining latch functionality and preventing power consumption.
Solution Approach 2:
The transmission module's operation is made dynamic based on the logic level of set and reset signals. When set or reset signals are at high level, the control module dynamically adjusts the transmission module's state to prevent current leakage paths while still allowing the latch function to operate. This dynamic control resolves the contradiction by adapting the system behavior to the signal conditions.
2Productivity
If the transmission module remains active during high level set/reset signals, then data transmission is maintained, but current leakage occurs between transmission module and latch module
Solution Approach 1:
The control module performs preliminary anti-action by detecting when set or reset signals are at high level and proactively controlling the transmission module to prevent current leakage paths before they can form. This preventive control stops the harmful effect of current leakage while maintaining data transmission functionality through proper signal management.
